Dear Mari

yes niacin is the one that can produce "flush" initially.

here is a mayo clinic article on the use of niacin (B3) for boosting HDL cholesterol:

but i found out B6 may in fact help me... apparently it helps keep cholesterol down... this says most of us don't get enough... so maybe it my LDL surge did have to do with my not taking my usual vits for so long!
